LSM6 SPI
Posted on July 29, 2015 at 20:12I'm trying to talk to a LSM6D3 over PCI. Everything's connected according to the datasheet in mode 1 (3.3v to VDD and VDDIO, SCx and SDx tied to GND) . I'm starting slow, so here's clock (SPC) and chip select (CS):htt...
Soft system reset on LSM9DS0?
Posted on April 09, 2015 at 01:12Since power cycle is not an option for my application, I'm curious if there's a way to do a soft system reset ('reboot') to the lsm9ds1 module? #lsm9ds0
LSM9DS0 axis orientation and readings
Posted on August 24, 2014 at 10:44Hi, I'm trying to understand the readings I got for a LSM9DS0 on my board. If I hold the board on my desk, according to the datasheet I should read a negative value for the Z-AXIS, because Z-AXIS vector points up, ...
LPS25H power consumption
Posted on June 16, 2015 at 08:38Hi, I use LPS25H in my project. Based on the application note AN4450 page 13,(example 1) when I configure the LPS25H to the mode that ODR is 25 Hz, pressure average 512, temperature average 64 (register 0x20 is 0xC0,...
